Fill-in-the blanks with the word(s) that best fit the description:

1. ____________________ coasts seaward edge the landward limit of the effect of the highest storm waves off the shore.

2. ____________________ the deflective force of earth's rotation on all free moving objects

3. ____________________ lowest tidal range occurring near the times of the 1st and 3rd quarter phases of the moon.

4. ____________________ a barrier constructed to prevent waves from reaching the area behind the wall. its purpose is to defend property from the force of breaking waves.

5. ____________________ highest tidal range that occurs near the times of the new and full moons

6. ____________________ the line that marks the contact between land and sea. It migrates up and down as the tide rises and falls.

7.____________________ a collective term of breakers also the wave activity in the area between the shoreline and the outer limit of breakers

8.____________________ movements of ocean water caused by density differences brought about by variations in temperature and salinity.

9. ____________________ a sandbar that completely crosses a bay sealing it off from the open ocean.

10.___________________ a low elongated ridge of sand that parallels the coast

11. ___________________ an accumulation of sediment found along the landward margin of the ocean or a lake

12. ____________________a partially enclosed coastal water body that is connected to the ocean. salinity here is measured reduced by the freshwater flow of rivers

13. ____________________ a near shore current that flows parallel to the shore

14. ____________________ seaward of the coast, this zone extends from the highest level of wave action during the storms to the lowest tide level.

15. ____________________ short wall built at a right angle to the shore to trap moving sand.

16._____________________ periodic change in the elevation of the ocean surface

17. _____________________ a ridge of sand that connects an island to the mainland or to another island

18. _____________________ horizontal distance separating successive crests or troughs.of waves.

19. _____________________ process by which the portion of a wave in shallow water slows. causing the wave to bend and tend to align itself with the underwater contours.

20. _____________________ an isolated mass of rock standing just off shore produced by wave erosion of a head land.
